Use symbol search name in expand_symtabs_matching_via_partial...

We are iterating over all symbols in a partial symtab that would
match a given name, so we should match the partial symbols
search name against the given name rather than using the natural
name. In C++, that does not make a difference, but it does in
Ada, because Ada searches using the symbol encoded name...

We also update the generation of the .gdb_index file to match this
change in the search. Although technically an incompatible change,
we do not increment the gdb_index version number, because Ada is
the only language where it would make a difference - except that
this feature is not supported for Ada.

gdb/ChangeLog:

* psymtab.c (expand_symtabs_matching_via_partial): Match
the partial symbols using their SYMBOL_SEARCH_NAME.
* symfile.h (struct quick_symbol_functions): Udate the
documentation of expand_symtabs_matching.
* dwarf2read.c (write_psymbols): Use SYMBOL_SEARCH_NAME instead
of SYMBOL_NATURAL_NAME in index entry.

Add handling for unqualified Ada operators in linespecs

This patch enhances the linespec parser to recognize unqualified
operator names in linespecs. This allows the user to insert a breakpoint
on operator "+" as follow, for instance:

(gdb) break "+"

Previously, it was possible to insert such a breakpoint, but one
had to fully qualify the function name. For instance:

(gdb) break ops."+"

gdb/ChangeLog:

* linespec.c (locate_first_half): Add handling of Ada operators
when the current language is Ada.

missing check against overlay_debugging in objfiles.c

This fixes a problem where the debugger is trying to locate a minimal
symbol from its address, when the symbol is inside a section whose
VMA is different from its LMA.

We have a program that was built on ppc-elf using a linker script
such that data sections are placed in ROM, and then loaded onto RAM
at execution. So their VMA addresses are indeed different from
their LMA address.

Unfortunately, there is one place where GDB gets slightly confused
into thinking that these data sections are overlayed, while it's
not the case here. This show up when trying to print the list of
Ada tasks, where GDB is unable to determine their names, and thus
prints a generic `Ravenscar task' instead:

(gdb) info tasks
ID TID P-ID Pri State Name
1 1d580 127 Delay Sleep Ravenscar task
2 183f8 127 Delay Sleep Ravenscar task
* 3 13268 127 Runnable Ravenscar task

We expected:

(gdb) info tasks
ID TID P-ID Pri State Name
1 1d580 127 Delay Sleep environment_task
2 183f8 127 Delay Sleep raven2
* 3 13268 127 Runnable raven1

The name of the task is determined by looking up the symbol table
using the task ID, which is the address where the symbol is defined.
So, ada-tasks calls...

msym = lookup_minimal_symbol_by_pc (task_id);

... which in turn first tries to determine the section associated
to this address (find_pc_section), which itself uses a map of sections
to find it. The map itself is recomputed every time objfiles are
loaded/changed by `update_section_map'. And `update_section_map'
relies on `insert_section_p' to determine whether the section should
be inserted in the map or not.

This is where things get interesting for us, because `insert_section_p'
simply rejects overlay sections:

if (lma != 0 && lma != bfd_section_vma (abfd, section)
&& (bfd_get_file_flags (abfd) & BFD_IN_MEMORY) == 0)
/* This is an overlay section. IN_MEMORY check is needed to avoid
discarding sections from the "system supplied DSO" (aka vdso)
on some Linux systems (e.g. Fedora 11). */
return 0;

However, it shouldn't reject our section in this case, since overlay
debugging is off. The fix is to add a check that overlay debugging
is active before rejecting the section. This is similar to what is
done in `section_is_overlay' (which takes obj_section objects), for
instance.

gdb/Changelog:

* objfiles.c (insert_section_p): Do not detect overlay sections
if overlay debugging is off.

[Ada] Breakpoints on task bodies

Consider the following declaration:

package Pck is
task Dummy_Task is
entry Start;
end Dummy_Task;
end Pck;

Inserting a breakpoint on the body of that task does not currently
work:

(gdb) b pck.dummy_task
"pck.dummy_task" is not a function
Make breakpoint pending on future shared library load? (y or [n]) n

What happens here is that the compiler generates two symbols:

(a) Symbol `pck__dummy_task' which is a *variable* referencing
the task;

(b) Symbol `pck__dummy_taskTKB' which is the subprogram implementing
the body of the task.

The symbol lookup only finds the variable before of the TKB suffix in
the subprogram name. This patch fixes the problem by adjusting the
ada-lang.c:is_name_suffix routine to recognize "TKB" suffixes. But
that's not enough, because the search in the symtab is performed via
the block dictionary, using a hashing algorithm. So, for the search
to find `pck__dummy_taskTKB', I had to modify the hashing function
to ignore TKB suffixes as well.

gdb/ChangeLog:

* ada-lang.c (is_name_suffix): Add handling of "TKB" suffixes.
Update function documentation.
* dictionary.c (dict_hash): Ignore "TKB" suffixes in hash
computation.

gdb/testsuite/ChangeLog:

* gdb.ada/task_bp: New testcase.
